Scans pinpoint moment anaesthetic puts brain under

24/10/2013, New Scientist online, Linda Geddes

Scientists at Oxford University investigating anaesthetics have found a new signature for unconsciousness. The discovery could lead to more personalised methods for administering anaesthetics and cut the risks associated with being given too high or too low a dose. In the study functional MRI revealed what was happening in different regions of the brain as they lost consciousness. One theory is that an anaesthetic switches off one of the brain's central relay hubs, the thalamus, meaning it no longer speaks to the cerebral cortex. However, Irene Tracey's team found that conversations between the cortex and the thalamus continued, even during deep anaesthesia – but there was no propagation of messages to wider regions of the brain. Importantly, the point at which messages stopped being routed out was the same point at which the slow-wave oscillations reached a plateau. The hope is that this "saturation point" could be used as a measure of when to stop administering drugs, to reduce the risk of side effects such as headaches, dizziness and memory loss.

Professor Irene Tracey of Oxford University is interviewed about new research in which scientists have identified the moment that anaesthetised patients become unconscious. Using imaging techniques, researchers examined the brain’s reaction to external stimuli whilst patients were slowly put under anaesthetic over a period of 45 minutes. They found that the point that the brain becomes isolated from the external world is different for each individual, a result which could lead to personalised dosing of anaesthetic prior to surgery.

The first of three special reports on a golden age of brain research, as dramatic advances across a range of fields raise the prospect of genuine breakthroughs in neurological disorders like Alzheimer's and Parkinson's disease. The piece looks at some of the hardware that has allowed neuroscientists to peek inside the ‘black box’ of the mind. Professor Irene Tracey of Oxford’s Nuffield Department of Clinical Neurosciences explains the difference functional magnetic resonance imaging of the brain has made. Oxford’s FMRIB centre has recently taken delivery of a new, even more powerful scanner: ‘They had to take the roof off the building to get the giant 40-tonne cylindrical magnet in,’ explains science correspondent Tom Feilden. Dr Stuart Clare puts Tom in the scanner then shows him an image of his brain. Professor Colin Blakemore of Oxford University discusses where this area of research could lead: ‘The excitement ... is around the combination of knowledge coming from genetics with new ways of manipulating genetic expression in cells, combined with imaging.’

Neuroscience May Transform Face Of War, Royal Society Panel Says

06/02/12, Huffington Post UK (via Reuters), Kate Kelland

Directed energy weapons that use wave beams to cause pain and electrical brain stimulation that boosts a soldier's combat ability could soon be with us according to a new Royal Society report. Irene Tracey, an expert on brain imaging from Oxford University and one of the report's authors, said most of the applications of neural interface technology, such as brain prostheses or implants, have so far been only at the trial stage and mostly in medicine. “You can imagine how this can be used for the military - both for rehabilitation of soldiers and for control of remote devices,” she told a briefing in London. “Some of it is the stuff of dreams at this stage, but the speed at which technologies tend to develop ... is always alarmingly quick.”

Why your expectations can be a real pain

13/11/2011, The Observer -Review-, p., p.21, Penny Sarchet

Penny Sarchet, a graduate student at Oxford University’s Department of Plant Sciences, writes about the ‘nocebo effect’ where warnings of fictional side-effects can make patients feel ill. The article highlights research by Oxford's Professor Irene Tracey which showed that when volunteers feel nocebo pain, corresponding brain activity is detectable in an MRI scanner. This shows that, at the neurological level at least, volunteers really are responding to actual, non-imaginary, pain.

Expectations affect benefits of pain drug

03/04/11, Chicago Tribune, p. 91, Kate Kelland

People who don't believe their pain medicine will work can actually reduce or even cancel out the effectiveness of the drug, and images of their brains show how they are doing it, scientists report. Researchers from Oxford University in Britain and Germany used brain scans to map how a person's feelings and past experiences can influence the effectiveness of medicines, and found that a powerful pain-killing drug with a true biological effect can appear not to be working if a patient has been primed to expect it to fail. By contrast, positive expectations about the treatment doubled the natural physiological or biochemical effect of an opioid drug among 22 healthy volunteers. “The brain imaging is telling us that patients really are switching on and off parts of their brains through the mechanisms of expectation — positive and negative," said Irene Tracey of Oxford University, who led the research.

Power of the mind can conquer pain

17/02/11, The Telegraph, p. 8, Stephen Adams

Pain really is all in the mind, according to scientists who have discovered that positive thoughts can double a painkiller's effect while negative thoughts can cancel them out. Researchers from Oxford, Cambridge and two German universities made their conclusions after a novel experiment examining the role of conscious thought in pain perception. Volunteers were asked to describe their pain levels when experiencing a pain device and being attached to a pain-reducing intravenous line, while at the same time brain activity was monitored using MRI scans. These showed their brains' pain networks were more active when they thought the drug was not being administered, while 'positive' thoughts that the painkiller was flowing inhibited such activity. Professor Irene Tracey from Oxford University led the research. She said: "People with chronic pain will often have seen many doctors and tried many drugs that haven't worked. They come to see the clinician not expecting to receive anything that will work for them."

Negative experiences can stop painkillers working

16/02/11, BBC News, James Gallagher

A patient's belief that a drug will not work can become a self fulfilling prophecy, according to researchers. They showed the benefits of painkillers could be boosted or completely wiped out by manipulating expectations. The study, published in Science Translational Medicine, also identifies the regions of the brain which are affected. Heat was applied to the legs of 22 patients, who were asked to report the level of pain on a scale of one to 100. They were also attached to an intravenous drip so drugs could be administered secretly. The initial average pain rating was 66. Patients were then given a potent painkiller, remifentanil, without their knowledge and the pain score went down to 55. They were then told they were being given a painkiller and the score went down to 39. Then, without changing the dose, the patients were then told the painkiller had been withdrawn and to expect pain, and the score went up to 64. Professor Irene Tracey, from Oxford University, told the BBC: "It's phenomenal, it's really cool. It's one of the best analgesics we have and the brain's influence can either vastly increase its effect, or completely remove it." Brain scans during the experiment also showed which regions of the brain were affected.

Feature article on the science of pain highlights the work of Professor Irene Tracey of Oxford University who is trying to develop an objective measure of pain based on people’s brain activity detected on an MRI scanner. Professor Tracey hopes such research will help in the understanding of chronic pain. She comments: ‘When you get conversion from the acute warning pain to the pain that goes on for years, there are new mechanisms that go wrong inside the brain - mechanisms that sustain and amplify it.’.

 

Drug makers give pain a closer look

Pain could become a disease in its own right, following the recognition of its significant cost to society and that the responses of the brain are central to pain. A study published last year by Irene Tracey of the Pain Imaging Neuroscience Group at Oxford University found that severe pain was linked to changes in the brain. She said, 'Pain doesn't exist until the brain gets hold of it.'
